To ctZZ whom t may concern.-

Be it known that I, EDWIN L. LLOYD, a citi-- zen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Bottle-Stoppers, of which the following is a specification.

The object of my invention is to provide a cheap and simple form of bottle-stopper designed to prevent refilling of the bottle, and this object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a sectional view of part of a bottlc-neck with stopper therefor constructed in accordance with my invention. Fig. 2 is a side elevation of the stopper detached from the bottle-neck. Fig. 3 is a view showing in elevation certain parts of `the stopper detached from each other. Fig. et is a view of the valve of the stopper in a different position from that shown in Fig. 1. Figs. 5, 6, and `7 are perspective views illustrating the construction of the valve of the stopper, and Fig. 8 is a view illustrating another form of stopper embodying my invention.

In Fig. l, A represents a tubular cork f1t-A ting snugly to the bottle-neck, the central opening of the cork receiving a tube a, preferably of glass, which has a flange or collar b, and above the same a smaller tube d, the latter fitting into the central opening of a cap B, but not extending to the top of said opening.

In the inner side of the wall of the opening in the cap B are formed a series of channels f, which communicate at their lower ends with a space C, formed between the flange b of the tube ct and the beveled under side of the cap B, other channels t', formed in the outer face of the cap B, also communicating with this space g, so that any liquid passing through the tube o, CZ into the opening of the cap B can find its way through the channels f, space g, and channels t', and can flow from the mouth of the bottle.

On the cap B are lugs or projections m for the support of a series of wires n., which, as shown in Figs. l and 2, are carried down on the outer side of the cork A and pass behind a label D, applied to said cork, the lower ends of the wires being bent upward on the outer side of the label, so that any attempt to remove the cap B will result in pulling the wires through the label, and will thus mutilate the same and show that the stopper has been tampered with.

In the lower portion of the tube d is fitted a tubular cork s, to which is secured, by means of an internal tube t, the lower portion of a tube w, of rubber, waterproof-cloth, or paper, or other available material of a ieXible character, the outer end of this tube forming lips which will open to any flow of liquid outwardly through the tube, but will close and prevent any iiow of the liquid into the tube.

The valve w is preferably constructed, as shown in Figs. 5, 6, and '7, by cutting a piece of Athin flexible waterproof material to the shape shown in Fig. 5 and folding it over upon itself on a line about midway of its length, as also shown in said figure. The projecting side iiaps w are then folded over upon and secured to the body, as shown inl Fig. 6, so as to form a tube having at the outer end flat lips to2, connected at the ends.

In one side of the tube are formed a series of openings w3 or other suitable form of vent, said vent being normally covered by a flapvalve 104, preferably of the same material as the main valve and secured in position by passing a stem w5 through an incision formed in the body of said main valve and cementing it in place on the inner side of the latter.

Secured to the free end of the flexible tubular valve 'w is a weight which when the bottle is inverted, so as to pour out its contents, will tend to `straighten said valve, as shown in Fig. 4.-, and permit of the escape of liquid therefrom; but when the bottle is held in an upright or upwardly-inclined position the valve will fall by gravity, sc as to cause the folding or kinking of the flexible tube, thus closing one side of the tube against the other and effectually preventing the inow of liquid through said tube.

When the bottle is inverted and the valve w. distended by the flow of liquid therethrough, air can pass beneath the valve 104 and through the openings w3, so as to enter the bottle as the liquid flows therefrom; but any IOO attempt to pass liquid into the bottle will cause the closing of the valve @U4 and the retention of the same in a closed position.

Avalve such as I have described is of cheap and simple character and has shown itself to be very effective for the purpose intended.

In that embodiment of my invention shown in Fig. 7 the opening in the cork A is decreased in diameter at the bottom, so as to provide for the reception of the inner portion of the valve w, and on the top of the cork rests a hollow cap B with three external channels i', each communicating at its lower end with a chamber Within the cap. This cap is intended to be secured in the bottle-neck by any suitable cement; but even in the absence of this method of fastening any attempt to remove the cap by means of a wire or other implement inserted in one of the channels fi will simply have the effect of tilting the cap so as to cause it to bind in the neck and prevent its removal therefrom.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. A bottle-stopper having a projecting valve consisting of a tube of flexible material secured at one end and provided at the free end with a weight, whereby the tube will be straightened when the bottle is held with the mouth downward, the weight falling by gravity when the bottle is held with the f mouth upward, so as to cause the folding or kinking of the exible tube, substantially as 5 specified.

valve with iexible lipped outlet, one or more air-inlet openings being formed in the valve behind said outlet, substantially as specified.

3. A bottle-stopper having -a projecting valve with flexible lipped outlet, said valve also having formed in it one or more air-inlet vopenings with Hap-valve for closing the same, substantially as specied.

4c. yA bottle-stopper having a projecting valve consisting of a strip of flexible waterproof material folded upon itself and having the edges united throughout a part of its length, the edges at and near the fold being free so as to form lips, substantially as specifled.

5. A bottle-stopper having a projecting valve consisting of a strip of waterproof niaterial folded upon itself and having overlapping edges throughout a portion of its extent, the portion in which the edges are not overlapped forming opposite lips, substantially as specified.

6. A bottle-stopper consisting of a tubular block having an external label visible through the bottle-neck, a detachable cap having prof EDWIN L. LLOYD.
